“…Six potential gas-phase components can be formed from the reaction between 13 CO 2 and 12 CH 4 , i.e., 12 conversion of 13 CO 2 and 12 CH 4 on the Pt-based catalyst, significant amounts of 12 CO and 13 CO were formed. Note that the concentration of 13 CO increased more rapidly than the one of 12 CO. As shown by the formation of water, RWGS occurred simultaneously and therefore, more CO was initially formed from 13 CO 2 than from 12 CH 4 .…”

“…It is obvious that at the high temperatures used for reforming, it is challenging to synthesize thermally stable catalysts and metal particles, which do not exceed the upper limit of 2 nm. Alternative conceptual approaches to enhance catalyst stability such as poisoning of the metal (SPARG process) and other means to reduce buildup of carbon at the catalyst have been vividly explored [9][10][11][12][13].…”

“…The addition of zirconia to catalyst materials reduces the carbon formation and the activity deactivation due to sintering [570]. Ceria remarkably prevents the formation of coke deposits and improves the catalytic activity and stability [571]. Magnesium incorporation increases the dispersion of the catalytic particles, enhancing activity and stability [572].…”

Innovative renewable routes are potentially able to sustain the transition to a decarbonized energy economy. Green synthetic fuels, including hydrogen and natural gas, are considered viable alternatives to fossil fuels. Indeed, they play a fundamental role in those sectors that are difficult to electrify (e.g., road mobility or high-heat industrial processes), are capable of mitigating problems related to flexibility and instantaneous balance of the electric grid, are suitable for large-size and long-term storage and can be transported through the gas network. This article is an overview of the overall supply chain, including production, transport, storage and end uses. Available fuel conversion technologies use renewable energy for the catalytic conversion of non-fossil feedstocks into hydrogen and syngas. We will show how relevant technologies involve thermochemical, electrochemical and photochemical processes. The syngas quality can be improved by catalytic CO and CO2 methanation reactions for the generation of synthetic natural gas. Finally, the produced gaseous fuels could follow several pathways for transport and lead to different final uses. Therefore, storage alternatives and gas interchangeability requirements for the safe injection of green fuels in the natural gas network and fuel cells are outlined. Nevertheless, the effects of gas quality on combustion emissions and safety are considered.

“…The addition of the Ce promoter to Ni increased the dissociation and CO 2 hydrogenation, and weakened the C=O bond of CO 2 adsorbed on the Ni active sites. Compared with the unpromoted Ni/ Al 2 O 3 catalyst, the addition of Ce strengthen the interaction between Ce and Ni, resulting in better activity of the Ce-Ni/Al 2 O 3 catalyst [58]. Doping the Ni-zeolites catalysts with 3-15% of Ce would be much more enhanced the catalytic performance than the unpromoted catalysts [41].…”

New Advances in Hydrogenation Processes - Fundamentals and Applications

With the accelerating industrialization, urbanization process, and continuously upgrading of consumption structures, the CO 2 from combustion of coal, oil, natural gas, and other hydrocarbon fuels is unbelievably increased over the past decade. As an important carbon resource, CO 2 gained more and more attention because of its converting properties to lower hydrocarbon, such as methane, methanol, and formic acid. Among them, CO 2 methanation is considered to be an extremely efficient method due to its high CO 2 conversion and CH 4 selectivity. However, the CO 2 methanation process requires high reaction temperatures (300-400°C), which limits the theoretical yield of methane. Thus, it is desirable to find a new strategy for the efficient conversion of CO 2 to methane at relatively low reaction temperature, and the key issue is using the catalysts in the process. The advances in the noble metal catalysts, Ni-based catalysts, and Co-based catalysts, for catalytic hydrogenation CO 2 to methane are reviewed in this paper, and the effects of the supports and the addition of second metal on CO 2 methanation as well as the reaction mechanisms are focused.
